Well, the idea just randomly came up in my head when I was writing the second chapter of the story, so I made her child hood a bit gloomy so that it could be one of the reasons as to why she was like that. I don't know anyone who is bipolar but I've done lots of research on it to see the symptoms and how a person with the disorder would behave on a regularly basis-that's why Tara's crying in most of the chapters, haha. Thanks for asking though! :D
